A BOLTORQ pressure gauge is a device used to measure the pressure of a fluid (gas or liquid) within a closed system. It typically consists of a dial or digital display that indicates the pressure reading, along with a mechanism such as a bourdon tube or diaphragm that senses the pressure and translates it into a readable form.

Here’s how it works:

• The pressure gauge is connected to the system containing the fluid whose pressure needs to be measured.
• As the pressure within the system changes, it exerts force on the sensing mechanism inside the pressure gauge.
• The sensing mechanism responds to this force by moving, which in turn causes a pointer to rotate around a dial or generates an electrical signal in digital gauges.
• The position of the pointer or the numerical value displayed on the gauge corresponds to the pressure of the fluid, usually measured in units such as psi (pounds per square inch), bar, or kPa (kilopascals).
• Pressure gauges come in various types and designs to suit different applications and pressure ranges, including analog gauges with dials and needles, digital gauges with numerical displays, and specialized gauges for specific industries or environments.
• Regular calibration and maintenance are necessary to ensure the accuracy and reliability of pressure gauge readings.
